Horsetail Fall, located in Yosemite Valley, is a seasonal waterfall that flows in the winter and early spring. The fall occurs on the east side of El Capitan and turns into mist before hitting the bottom of the ,540 foot drop giving it the name Horsetail Fall.
If Horsetail Fall is flowing in February and the weather conditions are just right, the setting sun illuminates the waterfall, making it glow orange and red. This natural phenomenon is often referred to as the “Firefall”, a name that pays homage to the manmade Firefall that once took place in Yosemite.
